Small Vacuum Pump of Selection

Small vacuum pump is also known as micro vacuum pump, because of its small size, so it is called small vacuum pump in the industry. It can not only achieve gas suction, but also achieve the effect of pressurization. With the increasing demand for small vacuum pumps in the whole market, the selection of small vacuum pumps has become a must for businessmen. In general, what are the precautions for the selection of small vacuum pumps?

Notices for Selection of Small Vacuum Pumps

1. Medium temperature of small vacuum pump.

According to the temperature of the medium gas passing through the pump, choose the ordinary type or the high temperature type.

2. Electromagnetic interference of small vacuum pump.

If there is a precise circuit to control the micro-pump, depending on the anti-interference ability of the circuit, it may be necessary to order a micro-pump with low electromagnetic interference.

3. Reliability of small vacuum pumps.

According to the severity of the consequences of the failure of small vacuum pumps, it is entirely in accordance with their own requirements. The average trouble-free continuous running time of high-quality products is more than 1000 hours, some as high as thousands of hours. Special attention is paid to the fact that this parameter is measured under full load and uninterrupted operation, which is the worst working condition. If the actual operation is not full load or continuous operation, the value will be higher, depending on the working condition of the pump.

4. Start-up with load.

If a small vacuum pump has a vacuum in its suction port or a pressure in its exhaust port before starting, another technical parameter of the pump should be considered: Pis value of the maximum start-up load at the intake port and Pos value of the maximum start-up load at the exhaust port. Typical application example is the use of micro air pump to maintain the vacuum or positive pressure in the container. When the vacuum or positive pressure in the container is lower than the set value, the pump needs to be energized to start and stop when it is higher than the set value.

If the user of small vacuum pump can make a correct judgment when choosing the product, I believe it will certainly provide great help for the future work and production. In recent years, China's economy and science and technology have made significant progress, I believe this will certainly provide a solid foundation for the development of small vacuum pumps. For the use of products, whether the original purpose can be achieved requires not only the good value of products, but also the wisdom of users.
